Canon RF 200-800mm F6.3-9 IS USM vs Canon RF 70-200mm F2.8 L IS USM

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Canon RF 70-200mm F2.8 L IS USM comes out ahead by a narrow margin (4.7 vs 4.8). The gap is mostly about Portrait, wedding, event and sports shooters who need a fast constant-aperture telephoto for low light and subject separation in a lighter-than-ever body. — read the strengths below before deciding.

Ranked #3 in Best Telephoto Lenses for Canon RF

Canon RF 200-800mm F6.3-9 IS USM

4.7

$2,049as of Jun 7

The Canon RF 200-800mm F6.3-9 IS USM delivers an astonishing 800mm of reach at a price that puts serious super-telephoto wildlife photography within reach of enthusiasts. Images are sharp with clean color, the 5.5 stops of stabilization are essential at these focal lengths, and the 4x range covers everything from 200mm to 800mm. The slow aperture and considerable bulk are the trade-offs for that reach.

Strengths

— Jaw-dropping 800mm of reach at a price that was unthinkable a few years ago
— Sharp, detailed images with clean color, ample for wildlife and the moon
— 5.5 stops of image stabilization that proves crucial at such long focal lengths

Watch-outs

— Variable f/6.3-9 aperture forces high ISO in dim conditions
— Large and heavy at about 2.05kg, demanding a substantial bag
— The tripod collar lacks built-in Arca-Swiss compatibility

Canon RF 70-200mm F2.8 L IS USM

4.8

$2,699as of Jun 7

The Canon RF 70-200mm F2.8 L IS USM reinvents the classic pro zoom for mirrorless, delivering the performance of a full-size 70-200mm f/2.8 in a package nearly 30% lighter and shorter. It is sharp wide open across the range, has class-leading stabilization, and pairs a constant f/2.8 with gorgeous bokeh. The trade-offs for that compactness are an extending barrel and no teleconverter support.

Strengths

— Beautifully sharp across the entire range, even wide open at f/2.8
— Nearly 30% lighter and shorter than the EF Mark III at around 1070g
— Exceptional image stabilization rated up to 7.5 stops with in-body IS

Watch-outs

— Externally zooming design extends the barrel and is less weather-resistant in concept
— Cannot accept teleconverters, so it is locked to its 70-200mm range
— Longer minimum focus distance than some rivals

How they stack up

Canon RF 200-800mm F6.3-9 IS USM

It offers the longest reach in this group by far, going to 800mm where the Canon RF 100-500mm F4.5-7.1 L IS USM stops at 500mm, and it is more flexible than the fixed Canon RF 800mm F11 IS STM. It is not as sharp or as bright as the RF 100-500mm L, and it gives up enormous light to the constant-f/2.8 Canon RF 70-200mm F2.8 L IS USM, but for pure budget reach it stands alone.

Canon RF 70-200mm F2.8 L IS USM

It is the low-light and portrait specialist of this group, the only lens here with a constant f/2.8 aperture, far brighter than the variable-aperture Canon RF 100-500mm F4.5-7.1 L IS USM, Canon RF 200-800mm F6.3-9 IS USM or Canon RF 100-400mm F5.6-8 IS USM. The trade-off is reach: it stops at 200mm and cannot take teleconverters, so it lacks the wildlife range of the others.
